The objective of this study is to apply the concept of structural health monitoring to the detection of bolted joints loosening without human involvement. The smart washer consists of the cantilever available to detect bolt loosening by using flexibility of cantilever and self-sensing/actuation function. The principle of how to detect the loosening of a bolt is the basis that the natural frequency of a smart washer system vary depending on a bolt tightening axial tension. Periodic maintenance of bolted joints is necessary to prevent an accident. The problems of periodic maintenance inspection with human-involvement are time-consuming, labor-intensive and high-cost. This paper is proposed that the remote health monitoring system by using smart washers. The remote health monitoring system is constructed by applying internet.
